It looks like glibc community won't review / push that change as it is in
freeze for glibc 2.26 cut right now accordingly to [1].

If my understanding is correct, it's a blocker or my change can be pushed
to elfutils and once glibc is open again (in about a week) I can submit
this elf.h change to libc-alpha@sourceware.org?


Thank you and best regards,
Gustavo
